Hi Im new here I have a 5 spd cobalt ls with 67k on the engine. I just picked up the car over the summer after my rx8 quit on me. now that im used to the ff platform again im missing the power I once had. I was wondering if the supercharger from an ss would fit my 2.2 ecotec. let me know and thank you

It will fit, there have been quite a few people that have done it including me and MP81, he has been running his with a 2.8 pulley for years with no problems but I snapped a rod after 8k miles with the same size pulley.. his is an 07 and mine is an 08, the guys at zzp seem quite sure that they used weaker rods in the 08 though
